MACHINE FOB EXTRACTING MOISTURE FROM CLOTH.

Specification o! Letters Patent.

Patented Nov. 3, 1914.

Application med December 20, 1912. Serial No. 737.803.

To all whom it may concern.' n

lle it known that I, DAvin Gassman, a citizen of the United States, residing at Worcester. in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Machines for llxtracting Moisture from Cloth, of which the following is a specification.

.\l v invention relates to certain im rove nients in hydro-extractora, in whici the liquor, or water, with which a fabric is saturated, is extracted by the vacuumproc ess. In all vacuuni-hydro-extractors used thus far b v the textile trade, the wet fabric is drawn over a stationary slotted tube, or over a chamber provide with a slotted mouth-piece, while a partial vacuum is being maintained in the tube, or chamber, by uuans` of a pump. The larger capacity pump one uses, the greater wil be the vacuum. and hence the more thoroughly will the extracting be done. However, as the vacuum increases, the friction and pull upon the cloth. too, increases, as the latter is dragged over the slot of the vacuum charnlier. which gives rise to a great many difficulties which I need not here set forth. 'lhey are snflicient, however, to practicall exclude the use of such machines on al light-weight fabrics, so that these machines can he used satisfactorily only on heavyweight fabrics that can stan the severe drag.1r over the stationary slot without being seriously a flectcd or injured thereby. Again, 'lwu a stationary cover is placed on top of the fabric where it passes over the slot, the friction and pull upon the fabric is yurea'tlv augmented, in fact. more than doul-h-d. because the cover not only uts considerable friction upon the top o the fabric where before there was none, but it likewise increases the vacuum Within the charnlwr. because it helps to better seal the slot [han would be possible if no cover were applied.

'l`o malte it possible to satisfactorilv extract a wet piece of light-weight fabric und at the same time eliminate the objectionable pull and friction put u on it by the existing vacuumapparntus, I ave constructed an entirely new vacuum-extractor, in which no friction whatever obtains, and which will extract the liquor or water from a heavy-weight fabric just as well as a lightweight fabric. To do this I dispense with the lixed slot in a stationary vacuiiincliainbei' altogether, and instead I employ a perforated suction-surface, which is moving with the cloth that is to be treated, and at the saine surface speed at which the cloth travels. l prefer to make the suction-surface circular. by using a hollow cylinder with an adequate number of holes drilled in itsI periphery, and its interior provided with a siphon. which is coupled to a pump, for creating a partial vacuum within the perforated cylinder and for eliininatin at the saine time the water therefrom, whic i is being extracted from the wet cloth during its travel around the suction-cylinder. I surround tlie suction-cylinder for a portion of its circumference with an endless apron. which travels in close contact with it, and outside of the cylinder the apron is drawn around a series of carrier-rolls that keep it in a smooth aiid extended condition. I cover the cylinder itself and its perfora tions with a few laps of cotton wrapper of a rather open weave, which will allow both water and air to pass freely throu h it. The endless apron, on the other hanf, is very closely woven or constructed, and while it may absorb and hold some water, 'yet it will exclude. air most efi'ectually, and in sonic cases it may be made entirely im er rions to both water and air. The wet c oth is passed between this closely woven endless apron surrounding the erforated cylinder and the cylinder itseli and is taken along by them as lsoon as the cylinder is set in motion. all three travelin in unison und at the same rateof speed. i o much of the cylinder ns is not under cover of the apron and would reninin exposed to view, is closed by an air-excluding shield, which fits this open circular section and although it does not actiiallv touch it, the air-space between the cylinder and the shield, however. is so trifiing. as to be a negligible quantity.

In the accompanying drawings and specification I have shown and described more fully the particular construction of my new improved apparatus that permits the extraction by the vaccum-process of the lightest weight fabrics that have baflled all past` attempts of machine builders, and my ma chine, moreover, will handle also heavyweight goods, and as readily and successfully as light-weight goods.

The invention consists in the construction and improvements to be more fully described hereinafter, and the novelty of which will be. particularly pointed out and distinctly claimed.

I have fully and clearly illustrated my iuveiition in the accom ninying drawings to he talien as a part of tiis spccilicat-ion, and wherein Figure l shows an elevation of my new \aci|um extractor iii vertical central crossseetion. and viewed from the rear. Fig. 2 is an end view seen from the driving'end. Fig. Il .shows an cud view from the opposite end of Fi Y. L', with certain parts modilied, the modi ication being shown in detail in Fi 4 and Figs. G and 'i' show certain ielails of Fig. 2. Fig. 8 shows a diagram in section of a modified foiiii of my machine. li i) is a top view of the air-excluding shiel showing the ilat extensions or feet at its ends hv which it is supported when placed in worting position.

Referring to Fi 1, 1 and 2 are the mairiframes. or end-fiaines, of my machine, which are fastened together at the bottom hy the girds 3 and 4, and at the top by the '1rd and the tie-rod Mounted upon t e frames 1 and 2, is the perforated'vacnain-cylinder 7, revoliible in bearings 15 and 1l on the frames 1 and i2. The cylinder 'i' carries end heads 8 and i). Secured to the head 8, is the hollow trunnion 10, .sealed at its outer end by the gudgeon 12 having an extension 12', which carries the drivin pulley 13 and the sprocket-wheel Il. T ie larger of the two end heads, that is the head il, is preferably in the forni of a casting containing a neck-piece il', which revolves in said beariii l, and has fastened at its end a thiinb e or collar 16, with a slecve-extcnsion 17, to which is screwed a packing nui 1S, said tbimble and nut turning about a stationary tube 1U, which is fastened at one end to the vertical elbow .11. while the other end of said tube 19 is provided with a Siphon 20, reachin downward and terminating just below t e inner laittoni-siirfnce of the perforated vacuumcylinder 'i'. The said elbow 21 is secured tothe top of thc separator-chamber 22, which carries an upper exhaust-pipe 28 for the air, and narrows at its bottom into funnel shape, which opens into nn opening .2 for the discharge of the water, a cockcase 24 being attached to said chamber, within which cock-case turns a ta ier pocket-cock 24 which at its outer end nis fastened astiid Q5, and at the other carries the jack-shaft 2G. The stud 25. is sii ported, in a ringbenring 29, and can adjusted longitudinally by the nuts 80, threaded onto the stud Q5. The jack-shaft Q0 carries a Hengstcoupling 2T bolted to a second coupling 28 keyed to the counter' shaft 26 extending,r across the machine and revolving in bearings 31 and 32, fastened to the cross-bars 1 and 2' of the mainframes 1 and 2. At the drivino' end of the machine the counter-shaft 26, carries a sprocket-wheel 33, around which passes a s )rocket-chain 14', which is driven (sec Iig. 2) from the sproclntuvhcel 1l, fast upon the extension 12'. of the gudgeon 1L). screwed to the truimion l0, of the cylinder 'i'. 3i and do are idlers for the chain 14', one hein adjustable, so as to be used as a chain-tig itener, when desired; llaccd upon the bottoni irds 3 and 4, is a trough 3V). containin tie rolls 25T and 3S, under and around iv iich travels the endless apron (il). .\scending from the roll 3T. in the direction of the arrow. the apron (it), passes over aiid around the. entrance-roller 4T, and next around the vacnum-cylinder T, beneath and then over the latter, then around the exitroller 48, on over the top-roller 4i), over and past the bach-roller 50, and then down to the rear bottoni-roll 3S. rI`he frontal portion of the cylinder T. lying between the entrance-roller 4T, and the exit-roller 48, and not covered by the a )ron G0. is hooded by an air-excluding shield 'lliis shield 58, has horizontally runningf beveled edges, which reach well ander tie apron entrance und exit, while ut the ends the edges 0f the shield are curved and conform in their curvature to the circle of the cyln der, w'thout quite touchin the sinne. Ilowever, die edges all aromi( the shield lic so close to the cylinder as to leave a very nar row nir space between them, there being just enen h room to slide in a piece of cardboar as thick as an ordinary visiting card between the two.

The nir shield 58, (sec Fig. D) has [iat end-extensions 57, that are fastened to a ljustable slide-shoes 53. on inclined bracketsl 52, secured on the inner sides of the upright posts 5l, one of which stands on top of cach end frame. The angle of inclination of tinslide-shoes is such as to move the air-shield 58, radially toward, or away from, the cylinder 7, as the adjusting;r screws 52". in the arms 52', of the post-brackets 52, are turned one way or another, enabling the operator to thus set the shield in relation to the cylinder as accurately as circumstances may demand.

The exit-roller 48. turns` in sliding-hearY ings 59, dovetailed to the faces of u )ward projections 61, on the rollcr-earryiiig-haines (i2, which frames straddlc thil cylindre bearings on to) of the main-frames l and 2. These lidingculings 5i), have toothed iuilv's 59', engaging with pinions (i2-. upon a .shaft 62' extendin across the machine and rev ohible in theiearing brackets U3', fastened to the said upward projections ui. handwheel 64, is attached to this shaft GQ to turn it, and a pull-and-catch pin 7i, in the li ll ber. suction means connected to said member, and an apron for causing a piece o f fabric to travel in contact with said member.
